Explanation:
Acceleration is change in velocity over time.
a = Δv / Δt
a = (18.0 m/s − 0 m/s) / (6.00 s)
a = 3.00 m/s²
Momentum is mass time velocity.
p = mv
p = (8000 kg) (18.0 m/s)
p = 144,000 kg m/s
Answer:
The magnitude of the recoil is v = 1.95 m/s
Explanation:
The momentum of bullet
P = m*v
P = 0.0077kg x 860m/s
P = 6.622 kg m/s
Now using the law of conservation of momentum we have,
P1 + P2 = 0
Now solve to V2 to find the velocity of the rifle so:
m1*v1 + m2*v2 = 0
3.4kg*v1 + 6.622 kg m/s = 0
3.4 kg*v1= -6.622 kg m/s
v1 = 6.622/3.4
v1 = 1.95 m/s
D- all of the above
is the answer
You need 5 blocks of the smaller object to contain the same amount of volume of the bigger object
Braking up to -8 meters per second squared is more risky than the other one.
<h3>What is inertia?</h3>
According to the definition of inertia, matter has the ability to remain at rest or to move uniformly in a single direction unless applied with an external force.
The ability of moving object to remain in moving uniformly in a single direction is called inertia of moving.
In this case, the car moving with certain velocity has inertia of moving. By certain applying brakes of more deceleration is more risky as it works opposite to the inertia of moving. Hence, braking up to -8 meters per second squared is more risky than breaking up to -3 meters per second squared.
As 8 meters per second squared acceleration or deceleration is larger compare to other; there may have no situation where it can be the opposite.
